Here is the dealio. There is this guy. He has a locker right next to mine. He isn't really popular, in fact, not many people think he's nice. He's sorta nice to me... I haven't had any major issues. He made it a point to talk to me. I don't know what's going on. He is in the same sports club as my brother, so I will see him a LOT. All I wanna do is find out if he likes me. Tips?
I've been in the same situation. A guy who isn't particularly nice randomly decided to talk to me a lot, but judging by the laughing of his posse when I reacted a little startled, I'm pretty sure he's playing a prank. My advice would be to treat him not differently than you would if you didn't think he liked you, and draw your conclusion based on how he continues to act. Hope I can help :)
Athena gave great advice. I don't really have anything to add.
That makes a lot of sense! I never thought of it that way! Thanks Athena and Zithia!
